Similarly, everyone is nervous about changes to the bits of the system that are considered critical: the file system, the public apis, the job scheduling. If you do want to get into the codebase -start with your own applications, follow through how they work in the in-JVM mini clusters, see how code is executed, data is read, etc. -look at the IPC infrastructure, serialization, and other things that are foundational. Even if you don't go near this code, you will see it often enough that you need to understand it. -if you want to do things like new scheduling, block placement algorithms, there are plug in points for these -so you can do stuff here without risk to anyone's working systems other than your own. -Otherwise: start with the small bugs that are irritating you. Even text messages, things there aren't enough tests for, diagnostics, etc. More diagnostics are things everyone needs -steve
